As a preferred technical solution of the present invention, the polypropylene filament thickness is 6-8D, and the polypropylene includes
The raw material of following parts by weight: 90-96 parts and 3-6 parts of uvioresistant master batch of polypropylene chip.
Compared with prior art, the attainable beneficial effect of the present invention is:
1, product has natural chemical stability, long service life；In addition to the concentrated sulfuric acid, concentrated nitric acid, not with other chemical reagent
Generate reaction.The product impregnates three days in 60 DEG C of calcium hydroxide solutions, and for strength retention almost up to 100%, polyester geotex-tile is strong
Power loss 10-15%, with the growth of soaking time, will continue to be hydrolyzed into disappearance.Poly- third long filament geotextiles adapt to various soil properties,
Aquatic environment adapts to use under conditions of various acid or alkali environments, guarantees the requirement of 50 years to 100 years service life of engineering.
2, quality is light, and intensity is high；Polypropylene density 0.91g/cm3, polyester density are 1.37g/cm3.Poly- third is common poly-
Close most light one kind of quality in object, thus same unit area, under quality condition, the number of fiber in polypropylene filament geotextiles
It is more.And the strength of unit is higher than polyester fiber 20-30%, has higher strength than polyester geotex-tile.Therefore, strength,
The functions such as isolation, anti-filter, holding are more superior, keep engineering safer；
3, Environmental security；Polyester hydrolysate terephthalic acid (TPA), belong to noxious material water body content be not to be exceeded 0.1mg/L and
1mg/L.Therefore consider from Environmental security angle, in the engineerings such as water conservancy, tunnel, draining, highway, railway.In foreign countries
It is not allow to apply, facile hydrolysis, hydrolysis do not generate noxious material to polypropylene filament geotextiles.Therefore polypropylene filament geotechnique
Cloth has excellent Environmental security performance；
4, product uniformity is good, and mechanical index is high, quality；Polypropylene filament spun-bonded non-woven, using international high-end production
Equipment and vanguard technology, make the product of production, and cloth cover is steady.Due to using slit drawing-off to replace traditional tubular drafting,
The generation of head silk, fault is prevented.Cloth cover each point uniform quality.Value≤2.6 CV%, each point stress is consistent, produces without weak spot
Raw, mechanical index is more than 30% or more similar product.
